Task: Display all Contact records Full Name from Contact entity where Status = Active and Order by Full Name

Solution: Follow the below steps,

Step 1: Open Visual Studio and Create Console Application Project.

Step 2: First we have to establish connection to CRM. Please follow my earlier post Connect to CRM Online or On-premise using C# SDK.

Step 3: Generate Early bound class using Crmsvcutil.exe. Please follow my earlier post Generate Early bound Class using CrmSvcUtil.Exe in CRM.

Step 4: Add EarlyBound.cs to the project.

Step 5: Include the namespace using EarlyBound.cs.

Step 6: Below code will retrieve records from Contact entity,

public static void retrieveContactRecords()
{
using (var context = new ServiceContext(_service))
{
var getContactRecords = from conSet in context.ContactSet
where conSet.StateCode == 0   //Check for Status == Active
orderby conSet.FullName
select conSet;

if (getContactRecords != null)
{
StringBuilder fullNameString = new StringBuilder();
Console.WriteLine("Full Name\n--------------------------");
foreach (var item in getContactRecords)
{
if (item.FullName != null)
fullNameString.AppendLine(item.FullName);
}

Console.Write(fullNameString);
Console.ReadKey();
}
}
}

Step 7: Final Code will be like below,

using Microsoft.Crm.Sdk.Messages;
using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Client;
using System;
using System.Collections.Generic;
using System.Linq;
using System.ServiceModel.Description;
using System.Text;
using System.Threading.Tasks;
using EarlyBound;

namespace LinqToCRM
{
class Program
{
static IOrganizationService _service;
static void Main(string[] args)
{
ConnectToMSCRM("arunpotti@MyOrg.onmicrosoft.com", "Password", "https://MyOrg.api.crm5.dynamics.com/XRMServices/2011/Organization.svc");
Guid userid = ((WhoAmIResponse)_service.Execute(new WhoAmIRequest())).UserId;

if (userid == Guid.Empty) return; // Check whether connection established or not

retrieveContactRecords();
}

public static void ConnectToMSCRM(string UserName, string Password, string SoapOrgServiceUri)
{
try
{
ClientCredentials credentials = new ClientCredentials();
credentials.UserName.UserName = UserName;
credentials.UserName.Password = Password;
Uri serviceUri = new Uri(SoapOrgServiceUri);
OrganizationServiceProxy proxy = new OrganizationServiceProxy(serviceUri, null, credentials, null);
proxy.EnableProxyTypes();
_service = (IOrganizationService)proxy;
}
catch (Exception ex)
{
Console.WriteLine("Error while connecting to CRM " + ex.Message);
Console.ReadKey();
}
}

public static void retrieveContactRecords()
{
using (var context = new ServiceContext(_service))
{
var getContactRecords = from conSet in context.ContactSet
where conSet.StateCode == 0   //Check for Status == Active
orderby conSet.FullName
select conSet;

if (getContactRecords != null)
{
StringBuilder fullNameString = new StringBuilder();
Console.WriteLine("Full Name\n--------------------------");
foreach (var item in getContactRecords)
{
if (item.FullName != null)
fullNameString.AppendLine(item.FullName);
}

Console.Write(fullNameString);
Console.ReadKey();
}
}
}
}
}

Step 8: Execute the project for the below output,
